INSERT large text amount gets truncated

Im trying to do a standard INSERT of over 8k of information into a mssql table via php. The funny thing is that mysql handled this perfectly and once i moved the system to mssql, i have had nothing but problems.

i know im not doing this right, im still very green when it comes to mssql, could someone please let me know how i can submit more then the alloted 8k to a mssql table without the info being chopped up after 8k.
